Program RSWWCOND - Locking entries

Dear All,

I am getting some problem with Program RSWWCOND. The execution of this program results in error 'Lock table overflow', due to which no user is able to login to the sap system.

I need to know what is the purpose/funtion of this program.Does it have something to do with workitems & why i am getting this error.

when the error occured we had around 10,000 workitems in our sap system.

The solution is to implement the sap note to increase table size to accomodate all the workitems,but i need to know the exact cause why it happens.

Please do help.

Thanks.
